Why the timing differs here

British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.

How to prune pole beans

Pinch or snip the growing tip at the desired height. Remove spent pods promptly to keep the plant productive; strip yellow or diseased leaves as they appear.

Pole beans are generally not pruned — they climb and produce continuously without intervention. Pinching the growing tip once the vine reaches the top of its support (typically 2–2.5 m / 6–8 ft) stops upward growth and can push energy into lower pods. Remove yellowing leaves and any diseased foliage throughout the season.

Why is UK pruning timing different from American advice?

Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
